I was experiencing frequent crash right after I enter any game mode in Battlefiled V with DXR ON. Now I have found a solution that does not require Windows clean install.
CPU : Intel Core i7 8700
GPU : GeForce RTX 2080 Ti (ASUS DUAL 11GB)
Memory : DDR4 32GB
Power: Seasonic 730W Platinum
OS: Windows 10 64bit home edition
After careful monitoring on performance during game, I found my game crashes when GPU temperature reached 80 degrees Celsius.
So I've tuned my GPU software (ASUS GPU Tweak II and EVGA Precision X1) to have 100% fan speed on 60 degrees Celsius. Then, the game is running smoothly and have not experienced crash since, with DXR ON.
Another minor problem I saw was CPU power throttle, when I turned on Ultra for graphic quality. Although GeForce RTX 2080 Ti is capable of Ultra quality, looks like there is a CPU bottleneck and there was frequent power throttle turned ON during the game which lead to crash even if GPU temperature was under 80 degrees Celsius. So to keep graphic capable for CPU to be handled, I used GeForce Experience optimization tool and set 4 level lower to what is recommended for GeForce RTX 2080 Ti.
It's a shame that I have to set lower graphic quality due to thermal and power issue. I will make sure to have water cooling on GPU and higher power cap next I built a high-end gaming PC.
